Question

Find the equation of the line passing through the given point and parallel to the given line.

( 1 , 9), y = 4
(-1 ,-3), y= 2
(4, -6), y = -5

Answer 1

y = 9, y = - 3 and y = - 6

Explanation:

a line with equation y = c is a horizontal line parallel to the x- axis.

c is the value of the y- coordinates the line passes through.

Thus parallel lines must also be horizontal with equation y = c

a line parallel to y = 4 passing through (1, 9 ) with y- coordinate 9 is

y = 9

a line parallel to y = 2 passing through (- 1, - 3 ) with y- coordinate - 3 is

y = - 3

a line parallel to y = - 5 passing through (4, - 6 ) with y- coordinate - 6 is

y = - 6
